How to continue using a powershell script after it finished-CodePudding

I don't know much about scripting at all, but want to help out my lead with something. I'm trying to create a script that will ask for a username and it will return when their password will expire in AD. I also want to continue inputting usernames after it has finished in case there are multiple users I need to check. Below is the script I have so far.

$User = Read-Host "Username?"
Get-ADUser $User -Properties "DisplayName", "msDS-UserPasswordExpiryTimeComputed" |
Select-Object -Property "Displayname", @{Name = "ExpiryDate"; Expression = {[datetime]::FromFileTime($_."msDS-UserPasswordExpiryTimeComputed")}}

I was looking into doing loops, but I do not know how to write it out. Any help would be appreciated. Thanks.

CodePudding user response：

You could use a do-until loop:

do {
    $User = Read-Host "Username? (enter 'q!' to quit)"
    if($User -notin @('', 'q!')){
        Get-ADUser $User -Properties DisplayName,"msDS-UserPasswordExpiryTimeComputed" | Select-Object -Property Displayname, @{Name = "ExpiryDate"; Expression = {[datetime]::FromFileTime($_."msDS-UserPasswordExpiryTimeComputed")}}
    }
} until ($User -eq 'q!')

PowerShell will continue to repeat the code inside the do block as long as the user doesn't input q!. The if statement also prevents attempts to fetch a user when no username was provided.

you could also use a while loop

while($true){
  $User = Read-Host "Username?"
  Get-ADUser $User -Properties "DisplayName","msDS-UserPasswordExpiryTimeComputed" | Select-Object -Property "Displayname", @{Name = "ExpiryDate"; Expression = {[datetime]::FromFileTime($_."msDS-UserPasswordExpiryTimeComputed")}}

  if($User -eq "q!"){
    break
  }
}

to quit the while loop enter "q!" in place of a user
